CHARLES H. DOWNES, OF JERSEY CITY, NEW JERSEY.

STYLOGRAPHWIC FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 232,633, dated September 28, 1880. Application filed July 24, 1880. N0 model.)

To all whom it may concern:

Be it known that I, CHARLES H. DOWNES, of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Stylographic Fountain-Pens, of which the following is a specification.

The object of my invention is to improve stylographic fountain-pens, first, by the employment of a beveled tube, which is pointed like a quill pen, in combination with a needle or clearer, which is allowed to receive endwise motion, and which passes from an ink-receptacle directly through said quill or writing-tube, as will be hereinafter explained; second, in a writing-point which is made separate from the point-section of the penhandle, and so formed that it can be fitted tightly in its place in the point-section and readily removed therefrom when it is desired to replace one writing-point by another one, as will be hereinafter explained. I attain these objects by the means illustrated in the annexed drawings, in which- Figure l is an external view of my improved pen. Fig. 2 is an external view of the writing-- point detached from the point-section. Fig. 3 is an enlarged sectional view of the f0un \tain-pen, the upper part of which is broken away. Fig. 4 is an enlarged sectional view of the writing-point.

Similar letters refer to similar parts throughout the several views.

A designates a small tube, which may he made of any suitable metal or combination of metals, and which has a writing-point formed by beveling one end, as shown at a in the annexed drawings.

When the small tube A is finished it resem' bles a very small writing pen or quill with a tubular sheath, and, if desired, its point may be slitted and tipped with platinum, iridium, or other suitable metal. This writing-point A is suitably secured into a cylindro-conical portion, B, which may be made of hardened rubber, metal, or other material adapted for the purpose, and its cylindrical portion may or may not have a screw-thread formed on it.

The portion B, having the tubular pen or quill fixed in it, as shown, is applied tightly,

but removably, to the tapered end of a pointsection, 0, which is tubular, and whichis applied to the hollow fountain-handle D of the pen.

E designates an air-tube which is arranged in the ink-receptacle, and which communicates with the external air near its upper end. The air which tube E receives is discharged into the ink-receptacle at b, for the purpose of allowing ink to flow from the writing-point during the act of writing.

The lower portion of the air-tube E has a needle or clearer, a, suitably applied to it, which isallowed to receive free endwise movement for the purpose of inducing a flow of ink to the writing-point and for keeping the sheath of the quill free from clogging.

The needle or clearer 0 may or may not be tipped with iridium or other suitable substance, and it extends down through the tubular portion or sheath of the quill A and protrudes slightly from the beveled writing-point of this tube, as clearly shown in several views of the drawings.

If the needle 0 is tapered, as shown in Fig. 3, and a corresponding tapered bore is formed. in the point-section or writing-point, the needle, when in repose, will be seated like a valve in the point-section or writing-point, and thus prevent the escape of any ink therefrom when the pen is not in use.

It will be seen from the above description that I have invented a fountain-pen the writing or pen point of which will be constantly and freely supplied with ink from the reservoir-handle during the act of writing. It will also be seen that the pen can be provided with a writing-point as fine or coarse as may be desired, and that the point may be slitted like a common writing-pen, so as to afford a degree of flexibility and the facility of making coarse or hair lines.

By the second feature of my invention an impaired or useless writing-point can bereadily detached from. the point-section O and a new writing-point substituted.

In practice I shall sometimes dispense with an air-tube, E, as I find that air will enter at the beveled end a of the quill in sufficient quantities to allow the ink to escape freely from the reservoir. shall alsoform the pointbined with a point, B, and adapted for use section 0 on a rod on which it will be vulwith a point-section and aneedle Orelearer 0f canized, thus saving expense of boring it out). a fountain-pen, substantially as described. 10

The section B may also be formed in the same CHARLES H. DOWN ES.
